…There is a Slight Risk of excessive rainfall over parts of the Western
Gulf Coast on Monday, expanding into the Central Gulf Coast by Tuesday…
…Dangerous heat continues to impact portions of southern California and
the Southwest through Monday…
…There are Excessive Heat Warnings and Heat Advisories over parts of
Southern California and the Southwest…
A quasi-stationary front will linger along the Gulf Coast through Tuesday.
Tropical moisture pooling along the boundary will also create showers and
thunderstorms through Tuesday. On Monday, the showers and thunderstorms
will produce heavy rain over parts of the southern Texas Coast. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over
parts of the Western Gulf Coast from Monday into Tuesday morning. The
associated heavy rain will create mainly localized areas of flash
flooding, with urban areas, roads, small streams, and low-lying areas the
most vulnerable.
Moreover, on Tuesday, the showers and thunderstorms with heavy rain will
expand along the Western Gulf Coast into the Central Gulf Coast.

Meanwhile, weak monsoonal moisture will aid in producing showers and
thunderstorms over parts of the Great Basin and Central/Southern Rockies
from the late afternoon into the late evening on Sunday and Monday. In
addition, weak upper-level energy over the Northern Intermountain Region
will produce scattered showers and thunderstorms overnight Sunday and over
parts of the Northern Plains/Upper Mississippi Valley overnight Monday
into Tuesday.
Additionally, upper-level ridging over the parts of Southern California
and the Southwest Plains will allow high temperatures to be in the upper
90s and low 100s, prompting Excessive Heat Warnings and Advisories over
parts of the region. Additionally, with low temperatures in the lower 80s
and upper 70s, little relief from the heat will occur overnight.
Therefore, people spending more time outdoors or in a building without
cooling in areas with heat warnings are still at an increased risk of
heat-related illness.
